The work represents continuation of the previous contract which encompasses five areas: (1) continued refinements and applications of the 2-D chemistry-transport model (CTM) to assess the ozone effects from aircraft operation in the stratosphere; (2) studying the mechanisms that determine the evolution of the sulfur species in the aircraft plume and how such mechanisms affect the way aircraft sulfur emissions should be introduced into global models; (3) the development of diagnostics in the AER 3-wave interactive model to assess the importance of the dynamics feedback and zonal asymmetry in model prediction of ozone response to aircraft operation; (4) the development of a chemistry parameterization scheme in support of the global modeling initiative (GMI); and (5) providing assessment results for preparation of national and international reports which include the "Aviation and the Global Atmosphere" prepared by the Intergovernmental Panel on Climate Change, "Assessment of the effects of high-speed aircraft in the stratosphere: 1998" by NASA, and the "Model and Measurements Intercomparison II" by NASA. Part of the work was reported in the final report. We participated in the SAGE III Ozone Loss and Validation Experiment (SOLVE) campaign and we continue with our analyses of the data.Ko, Malcolm and Weisenstein, Debra and Danilin, Michael and Scott, Courtney and Shia, Run-LieGoddard Space Flight CenterCLIMATE CHANGE; DIAGNOSIS; MATHEMATICAL MODELS; OZONE; PARAMETERIZATION; TWO DIMENSIONAL MODELS; ASYMMETRY; FEEDBACK; FLIGHT OPERATIONS; LOSSES; PLUMES; STRATOSPHERE; SULFUR; SUPERSONIC AIRCRAFT
